3.0 THRU-HULL CAMERA ASSEMBLY INSTALLATION
1. Measure the position of the cameras, mark carefully, and double-check for internal obstacles.
2. Confirm there is clearance (more than 7
”) inside the hull to be able to remove the Camera Insert Module.
3.
Drill a 2-1/4 inch (57 mm), perpendicular hole through the hull.
Note: The required hole size will change when using an isolation sleeve, refer to the isolation sleeve instructions,
supplied with the sleeves, for further information.
4. The exposed inner hull surface must be properly sealed to prevent water intrusion into the hull before the Thru-Hull
is secured in place.
5. Before inserting the Thru-Hull Camera Assembly ensure that the hull surface is free from dirt and grease and
remove any existing anti-foul from the hull surface.
Note: Do not use an alcohol-based solvent as this may have an adverse effect on the sealant.
TO ALIGN THE PICTURE - MAKE SURE THE "TDC" ON THE BACK OF THE CAMERA MODULE IS AT THE
TOP CENTRE OF THE THRU-HULL CAMERA ASSEMBLY WHEN IT IS INSERTED.
5. Using an approved adhesive (3M 4200 Marine or similar), apply liberally a continuous bead of sealant around the
entire circumference of the sealant groove, on the base of the stem, and on the shaft of the thru-hull.
6. Gently insert the stem of the Thru-Hull Camera Assembly through the hole in the hull.
7. Apply gentle even pressure with a slight circular motion until the Thru-Hull housing is flush with the hull surface.
8. From inside the vessel, feed the supplied rubber washer down the shaft of the Thru-Hull fitting. Screw the locking
nut in place and tighten hand tight.
Do not tighten fully at this stage, excess pressure will push all of the
sealant out.
9. Remove excess sealant that is squeezed from behind the camera with a rag.
10. Allow the sealant to cure according to the sealant manufacturer
’s instructions. Once fully cured, tighten the locking
nut.
Hand tight only - excessive force can cause damage to the camera module or to the hull of the vessel.
11.
Attach the vessel’s bonding protection to the bonding bolt on
the rear of the locking nut.
!! IMPORTANT:
●
Ensure that each camera module has correct vertical and horizontal alignment with the hull. Ensure the
"TDC" on the rear of the camera is at the top centre.
●
Before launching the vessel the sealant should be checked to ensure it is fully cured in accordance with
the manufacturer
’s instructions.
